Effect of warfarin on activated partial thromboplastin time.
BACKGROUND The activated partial thromboplastin time (APTT) is used to adjust heparin sodium dosage. However, warfarin sodium is often administered concomitantly with heparin and may also affect the APTT and, therefore, heparin dose. We performed a prospective cohort study to quantify the effect of warfarin on the APTT in patients who are being treated with heparin. METHODS Serial assays of A...
متن کاملLaboratory Methodologic Approach in Prolonged Activated Partial Thromboplastin Time Test
The pathological activated partial thromboplastin time test is a data that we can find in all clinical laboratories routinely. The hemato-coagulative clinical case here reported aims to point out how the laboratory can provide a correct diagnosis by methodological rational setting and, consequently, carry out an appropriate therapy, or reassure the patient that the pathological data will not ca...
متن کاملThe effect of different nitrate preparations on plasma heparin concentrations and the activated partial thromboplastin time.
There is evidence that intravenous nitrates which are frequently used in acute coronary syndromes may interfere with the anticoagulant effect of heparin. We compared the effect of two different nitrate preparations on the activated partial thromboplastin time (APTT), anti-thrombin III activity (AT III) and plasma heparin levels in patients (n = 50) undergoing routine percutaneous transluminal c...
متن کاملActivated partial thromboplastin time monitoring in patients receiving unfractionated heparin for venous thromboembolism in relation to clinical outcomes.
Venous thromboembolism (VTE) is a prevalent and serious condition, which requires anticoagulation treatment for prolonged time duration. The use of unfractionated heparin administered intravenously or subcutaneously for acute management of VTE has been studied with favourable clinical results. Most physicians use activated partial thromboplastin time to monitor the treatment effect, in an effor...
متن کاملEvaluation of Antiphospholipid Antibodies and Activated Partial Thromboplastin Time in Women with Adverse Outcome of Pregnancy
Adverse outcome of pregnancy is a potentially dangerous complication of conception and affects 15-20% of pregnancies. According to recent studies increased level of blood antiphospholipids antibodies, if accompanied by predisposing factors, can be an adverse event in human pregnancy. The aim of the present study was to compare the maternal serum levels of anticardiolipin and antiphosphatidyl se...
